I am using a HL7800 with FW 3.5.0 on Linux and experimenting with its USB interface since I would prefer it over UART. I am not able to get anything out of its ttyACM interface and trying to debug the issue. What i noticed is that I have “strange” USB ID’s:
When KUSBCOMP was at 0, I had:
Bus 002 Device 002: ID 216f:0051
Since KUSBCOMP is set to 1, I have:
Bus 002 Device 003: ID 216f:0060
From the AirPrime_HL78xx_AT_Commands_Interface_Guide_Rev9_3 I would have expected to only see ttyACM interface(s) with KUSBCOMP=1. Also the above document states that the PID should be 0xC001 which does not apply to either case. Any ideas what might be going on here?
